Biomedical engineers have demonstrated a new approach to making self-assembled biomaterials that relies on protein modifications and temperature. The hybrid approach allows researchers to control self-assembly more precisely, which may prove useful for a variety of biomedical applications, from drug delivery to wound-healing.

A new theory about how oceans and volcanoes interacted during the early history of Mars supports the idea that liquid water was once abundant and may still exist underground. Geophysicists propose that the oceans originated several hundred million years earlier than thought, as the volcanic province Tharsis formed, and that greenhouse gases enabled the oceans. The theory predicts smaller oceans, more in line with estimates of water underground and at the poles today.

Two novel materials, each composed of a single atomic layer and the tip of a scanning tunneling microscope - these are the ingredients to create a novel kind of a so-called 'quantum dot'. These extremely small nanostructures allow delicate control of individual electrons by fine-tuning their energy levels directly. Such devices are key for modern quantum technologies.

It defies conventional wisdom about semiconductors. It's baffling that it even works. It eludes physics models that try to explain it. This newly tested class of light-emitting semiconductors is so easy to produce from solution that it could be painted onto surfaces to light up our future in myriad colors shining from affordable lasers, LEDs, and even window glass.

Recent developments in neuroscience set high requirements for sophisticated data management, not least when implantable Brain Machine Interfaces are used to establish electronic communication between the brain's nerve cells and computers. A new method makes it possible to recode neural signals into a format that computer processors can use instantly.

Helium, a noble gas, was long believed to be 'too aloof' to react with the other elements on the periodic table. Now, however, scientists have provided a theoretical explanation of how helium may be capable of forming stable compounds.

The world drinks a lot of wine, and that means a lot of grapes are consumed. But not every part of the grape ends up in the bottle. Seeds, stalks and skins end up in landfills. Now, researchers say they have found useful commercial applications, such as prolonging the shelf life of fatty foods, for these wine leftovers.

Personalized medicine is one step closer thanks to tiny, implantable sensors that can send data to a computer or cell phone to give early warning of a person's developing health problems. Future versions of these devices could indicate the most effective type of exercise for an individual athlete, or help in the triage of wounded soldiers.

Medical professionals are scrambling to meet growing demand for emergency room treatment of drug overdoses, but they're hampered by the lack of a quick and easy test to screen patients for synthetic 'designer' drugs. Chemists are developing such a test with the hope that hospitals could eventually use it to choose the appropriate treatment.

By the time a Colonial Pipeline leak was detected last fall during a routine inspection, vapors from the quarter-million gallons of released gasoline were so strong they prevented pipeline repair for days. Now, scientists report technology that would alert pipeline managers about leaks much earlier, avoiding the environmental disasters and fuel distribution disruptions resulting from pipeline leaks.

The military uses smoke grenades to provide cover for people and tanks on the move. But the smoke arms race is on. Increasingly, sensors can now go beyond the visible range into the infrared (IR) region of the spectrum. So, researchers report developing a new kind of smoke that obscures both visible and IR detection.

Interactive virtual reality (VR) brings medical images to life on screen, showing interventional radiologists a patient's unique internal anatomy to help physicians effectively prepare and tailor their approach to complex treatments, such as splenic artery aneurysm repair, according to new research.

The online advertising business, led by companies like Google or Facebook, generated over $200 billion revenue in 2017, with an interanual growth over 15 percent. This online advertising explosion is raising serious data privacy concerns.
